Be it known thet- If, FRASE KLEPETKO. e citizen of the'United`Stfttes,res-ding at New York, in the county ofNe-rA York and State ofN'ew York, have invented certain new and useful. Improvements in :Roasting-Furnaces.

of,which theOllOWi-ng `is 'a full, clear,`and 'exact descriptiodreference being had t nthe accompanying rawi'ngs, forming a part hereof.. P Y' ments in roastinglm'naces ;and it consists in theV novel 'construct-ion end arrangement of parts more fully set forth inthe specification andpointed outinthe claims. l

The shaft is divided into a'series of com- Eartm'ents or chambers c1-b c d cfg. the 'cham'- ers being separated from one another by the 'transversely-disposed division walls or partitions' 9, occupyino' aplaneslivhtly above the bottoni of the exfacent rabb 4e-nrnisi,` each'.

Inj `otherwords, thecirculating medium discharges into the shaft at a point which is reinovefroni the outlet ordischaige thereof out of the shafts-a distance equal substantially to one-half the length of the shaft, or one-half the height ofthe furnace. In the event that the hot testl point of the f urnace Vshoiild `n'otbe precisely at the middle the introduction of Vthe water-'at substantially the middle of the shaft will result inthe forf. mation of two currents. which will readily adjustthemselves according tothe -temperatures to which they are most likely to respond in the-matter of direction and intensit It is-to he understood. ofcourse. that the feed-pipe 6 6" need not terminate preciselyv at the center of the length of theshaft. and a slight variation therefrom would not consti- 1 tute a departure from the invention -as long asg'the formation of two currentsflowing parallel in opposite direction through the shaft was insured. A

f-Such features andadvaritages of construe# tion to which no specific reference is herein made are either well known or covered' by the state of the art, and hence no description thereof is necessari i The cooling'apparatus need not necessarily be restricted in its application to roasting-furnaces, but may be' applied in other furnaces and kindred arts.4
